Complementarity between Axle Counters and Tracks Circuits
The infrastructure manager choice of type of the track vacancy detection system requires to be based on a safety and signalling functions analysis and not on a dogmatic position. The paper aims at showing that the two main families of these systems are complementary, each of them responding to particular needs in regard to the route category, the traffic duty and the accepted risk.
